James average was a 73 first semester and 88 second semester. find the percent change.

20.54%

Step-by-step explanation:

the first thing to know the percentage change, is to notice if the average increased or decreased, if it was initially 73 and then 88, we can say that increase, therefore the change is positive, now to calculate the exact change we must calculate the quotient of these numbers:

88/73 = 1.2054

which means that 0.2054 is the proportion of increase, to pass it to a percentage we must multiply by 100, that is:

0.2054 * 100 = 20.54%

which means that the percentage change was 20.54%

The percentage change = 20.55% ( increase)    

Step-by-step explanation:

First of all, we will find the change in score, and this is calculated as

Change in average = second semester average - first semester average

Change in average = 88 - 73 = 15

Next to find the percentage change, since we know the average change, we will calculate what percent of the original average is the average change. This is simply shown as follows:

Percentage change = (change in average) ÷ (original average) × 100

Percentage change = (15 ÷ 73) × 100 = 20.55% (increase)
